=====Testing Actions=====

In short:
  - Create a test item holding text.
  - Create a trigger to do a diff() on the text in the test item.
  - Connect your action to the trigger.
  - Use zabbix_sender from the Zabbix server (or another system) to set values.

=====Send HTML e-mails=====

By default Zabbix sends plaintext e-mails and has no builtin options to send HTML mail. \\
See: [[https://support.zabbix.com/browse/ZBXNEXT-517|ZBXNEXT-517 - Mail text as plain/HTML, only on demand]] \\

To be able te send HTML e-mail an external script is needed. \\
Several options exist:
  * [[https://www.viamage.com/blog/note/html-e-mails-zabbix|Viamage - HTML E-mails from Zabbix]] with sendEmail and a shell script.
  * [[http://va0816.blogspot.nl/2013/07/zabbix-htmlmail.html|IT Заметки - Отправлять оповещения с Zabbix письмами в формате HTML]] with mutt and a shell script. (Obviously not written in English, but the scripts and screenshots in de post are in English.)
  * [[https://wordpress.jpcorp.eti.br/?p=545|JPCorp – Jhones Petter - Zabbix – Media Types Email-Html “sendhtml.py”]] with libesmtp and a Python script.
